The iwatch loses 10% of its battery power overnight
< br >
A night of standby power failure within 10% is within the normal range.

According to the official instructions, the charging system architecture of the Apple Watch Series 7 has been upgraded with the USB-C fast charging cable, which takes only about 45 minutes to charge from zero to 80%, which is 33% faster than the Apple Watch Series 6. The actual test shows that the mophie 3-in-1 wireless charging base sold on Apple's official website is used to charge the Apple Watch that is running out of power, and the charge is less than 50% in an hour; Using the USB-C charging cable that came with the new Apple Watch, the charge went from 38% to 96% in just 40 minutes, which is really a lot faster.
The reason is that the iwatch will carry out some background operations in the standby state, such as monitoring the heart rate, updating the weather, etc., which consume power.
The standby time of a night is longer, and the power consumption is relatively large.
If you want to extend the standby time of the iwatch, you can turn off some infrequently used functions, such as the steady screen, email push, and so on. In addition, you can put the iwatch on the charging base when you sleep at night, so as not to affect the use of the next day.
Sleep with or without a watch, a night of electricity consumption is about 15%, up and down 4%.
The following is a 7-day power consumption test done in September, for reference only. In addition, it is generally recommended to charge once before going out in the morning and once after coming home at night (if you need to record sleep, and you also need to go out with a full charge, or even physical training). My energy consumption is down to 10% so far.
Standby power consumption for one night is about 30 percent, but the following methods can save power consumption.
Restart the Apple Watch first, then turn on the background refresh master switch in the iPhone Watch app, and then turn off all the program switches. After using this method, the airplane mode standby for one night, the power consumption is about 5%.
Depending on the use, because the iWatch in the standby state of different use conditions, the power consumption will be different.
If you turn off Bluetooth, Wi-Fi, heart rate detection and other functions in the standby state, the power consumption will be less in a night.
However, if you need to use functions such as alarm clocks and reminders, the power consumption will increase accordingly in the standby state.
If you want to extend the standby time of the iWatch, you can turn off Bluetooth, Wi-Fi, heart rate detection and other functions when you are not using the iWatch, and you can also reduce the screen brightness and other ways to save power.
The Apple watch consumes about 20% of its power when it is standby for one night! If your Apple watch supports power-saving mode, it will consume about 10% of your battery power in one night. This is because the iWatch has a small battery capacity
